Description

本発明は、被溶着物の容器を開封した時に、容器に形成した溶着突起によって仮止めをすることができる超音波溶着器に関するものである。   The present invention relates to an ultrasonic welder that can be temporarily fixed by a welding protrusion formed on a container when the container to be welded is opened.

従来、超音波溶着器は、図５に示すように、上部支持部材１と下部支持部材２の一方の端部に突出部１ａ、２ａを設け、この突出部１ａ、２ａに回動軸３を装着し、この回動軸３から離れた位置にバネ４を設け、又、上部支持部材１の他方の端部から振動端５ａが突出するように超音波振動子５を装着し、下部支持部材２に他端にアンビル６を装着し、超音波振動子５の振動端５ａとアンビル６の間に被溶着物７を挿入し、振動端５ａとアンビル６を互いに押し付け合うことにより、超音波振動が発生し、振動端５ａとアンビル６との間に挿入された被溶着物７を溶着するようにしたものが提案されている。   Conventionally, as shown in FIG. 5, the ultrasonic welder is provided with protrusions 1a and 2a at one end of an upper support member 1 and a lower support member 2, and a rotation shaft 3 is provided at the protrusions 1a and 2a. A spring 4 is provided at a position away from the rotating shaft 3, and the ultrasonic transducer 5 is mounted so that the vibration end 5 a protrudes from the other end of the upper support member 1, and the lower support member 2, the anvil 6 is attached to the other end, the welded material 7 is inserted between the vibration end 5 a of the ultrasonic transducer 5 and the anvil 6, and the vibration end 5 a and the anvil 6 are pressed against each other, thereby ultrasonic vibration. Has occurred, and the object 7 to be welded inserted between the vibration end 5a and the anvil 6 is welded.

しかしながら、この超音波溶着器では、図６に示すように、アンビル６の上面６ａは平らに構成されるとともにぎざぎざが設けられ、又、超音波振動子５の振動端５ａの下面はアンビル６の上面と対応して平らにしているため、上部支持部材１と下部支持部材２を押して、超音波振動子５の振動端５ａとアンビル６の上面６ｂとで被溶着物７を溶着すると、被溶着物の容器は蓋を開いた時に固定するものがないので、輪ゴムや紐で容器の蓋を閉じなければならなかった。
特願２００２−２２８２５３ However, in this ultrasonic welder, as shown in FIG. 6, the upper surface 6 a of the anvil 6 is configured to be flat and provided with jaggedness, and the lower surface of the vibration end 5 a of the ultrasonic vibrator 5 is formed on the anvil 6. Since the upper support member 1 and the lower support member 2 are pushed and the welded object 7 is welded by the vibration end 5a of the ultrasonic transducer 5 and the upper surface 6b of the anvil 6, the upper support member 1 and the lower support member 2 are pressed. Since there is nothing to fix when the lid is opened, the container lid had to be closed with a rubber band or string.
Japanese Patent Application No. 2002-228253

解決しようとする問題点は、被溶着物の容器を開封した時に、容器の蓋を仮止めすることができないことである。   The problem to be solved is that the lid of the container cannot be temporarily fixed when the container of the object to be welded is opened.

本発明では、アンビルの上面に超音波振動子の振動端が挿入される挿入穴を儲けることにより、超音波振動子の振動端とアンビルの間に被溶着物の容器の蓋の端部を挟んで超音波振動子の振動端をアンビル方向に移動すると、超音波振動子の振動端の超音波振動で柔らかくなった被溶着物がアンビルの挿入穴に押し込まれ、それによって被溶着物の溶着突起が容器の蓋の周囲に形成されるので、容器の蓋を開いた後で、蓋の両側の溶着突起を合わせて挿入することにより、容器の蓋を仮止めすることができる。   In the present invention, an end of the lid of the container to be welded is sandwiched between the vibration end of the ultrasonic vibrator and the anvil by making an insertion hole into which the vibration end of the ultrasonic vibrator is inserted on the upper surface of the anvil. When the vibration end of the ultrasonic vibrator is moved in the anvil direction, the object to be welded softened by the ultrasonic vibration at the vibration end of the ultrasonic vibrator is pushed into the insertion hole of the anvil, thereby welding the protrusion of the object to be welded. Is formed around the lid of the container, and after opening the lid of the container, the lid of the container can be temporarily fixed by inserting the welding projections on both sides of the lid together.

本発明の超音波溶着器は、アンビルの上面に超音波振動子の振動端が挿入される挿入穴を儲けることにより、被溶着物の容器の端部を溶着した時に、溶着突起が形成され、この溶着突起は剥がして蓋を開いた後に、再び閉じることができ、輪ゴムや紐等の他の仮止め物を使用する必要がないという利点がある。   In the ultrasonic welder of the present invention, a welding projection is formed when the end of the container of the object to be welded is welded by making an insertion hole into which the vibration end of the ultrasonic vibrator is inserted on the upper surface of the anvil. This welding projection can be peeled off and the lid can be opened, and then closed again, and there is an advantage that it is not necessary to use other temporary fixing materials such as rubber bands and strings.

図１は本発明の実施例の超音波溶着器の構成図で、１は上部支持部材、２は下部支持部材、３は回動軸、４はバネ、５は超音波振動子、６はアンビル、７は被溶着物であり、これらの構成は上記従来例と同じであるので、説明は省略するが、本実施例では、超音波振動子５の振動端５ｂの面積を従来例より小さくし、又、アンビル６を上面６ｂから超音波振動子５の振動端５ｂが挿入される挿入穴６ｃを形成し、この挿入穴６ｃは超音波振動子５の振動端５ｂの径より大きく形成する。   FIG. 1 is a configuration diagram of an ultrasonic welder according to an embodiment of the present invention. 1 is an upper support member, 2 is a lower support member, 3 is a pivot shaft, 4 is a spring, 5 is an ultrasonic transducer, and 6 is an anvil. , 7 are to-be-welded objects, and since these structures are the same as those of the conventional example, description thereof is omitted. In this embodiment, the area of the vibration end 5b of the ultrasonic transducer 5 is made smaller than that of the conventional example. The anvil 6 is formed with an insertion hole 6c into which the vibration end 5b of the ultrasonic transducer 5 is inserted from the upper surface 6b. The insertion hole 6c is formed larger than the diameter of the vibration end 5b of the ultrasonic transducer 5.

このように構成された本実施例の超音波溶着器では、超音波振動子５の振動端５ｂとアンビル６の間に被溶着物の容器７の上下の端部７ａを載置して、上部支持部材１及び下部支持部材２を挟持することにより、電源がオンとなり、振動端５ｂとアンビル６の間で被溶着物の容器７の端部７ａが加圧されて被溶着物の端部７ａが超音波振動で溶融され、さらに、超音波振動子５の振動端５ｂが押し込まれることにより、被溶着物の端部７ａはアンビル６の挿入穴６ｃに押し込まれて塑性変形され、図２に示すように、容器７の端部７ａに溶着突起７ｂが形成される。   In the ultrasonic welder of the present embodiment configured as described above, the upper and lower ends 7a of the container 7 to be welded are placed between the vibration end 5b of the ultrasonic transducer 5 and the anvil 6, and the upper portion By sandwiching the support member 1 and the lower support member 2, the power is turned on, and the end 7 a of the container 7 to be welded is pressurized between the vibration end 5 b and the anvil 6, and the end 7 a of the welded object is pressed. 2 is melted by ultrasonic vibration, and further, the vibration end 5b of the ultrasonic vibrator 5 is pushed in, so that the end 7a of the welded object is pushed into the insertion hole 6c of the anvil 6 and is plastically deformed. As shown, a welding projection 7 b is formed on the end 7 a of the container 7.

このように形成された容器７の上下の端部７ａの溶着突起７ｂは内側だけが接着されているので、それを剥がすと、塑性変形された溶着突起７ｂが容器７の上下の端部７ａにそれぞれ残るので、容器７を開封した後、端部７ａに形成された溶着突起７ｂを互いに合わせて、一方の溶着突起７ｂを他方の溶着突起７ｂに挿入すると、この溶着突起７ｂの形成時に溶着突起は互いに密着しているので、剥がして溶着突起７ｂを互いに挿入しても、簡単に抜けることがなく、抜け止めの効果を十分発揮することができる。   Since the welding projections 7b of the upper and lower end portions 7a of the container 7 formed in this way are bonded only on the inner side, the plastic-deformed welding projections 7b are formed on the upper and lower end portions 7a of the container 7 when peeled off. After the container 7 is opened, the welding projections 7b formed on the end portion 7a are aligned with each other, and one welding projection 7b is inserted into the other welding projection 7b. When the welding projection 7b is formed, the welding projection 7b is formed. Since they are in close contact with each other, even if they are peeled off and the welding projections 7b are inserted into each other, they do not come off easily, and the effect of retaining them can be sufficiently exerted.

図３は本発明の他の実施例の超音波溶着器の拡大構成図で、２は下部支持部材、５ｂは超音波振動子５の振動端、６はアンビル、６ｃは挿入穴、７は被溶着物の容器、７ａは端部であり、これらの構成は上記実施例と同じであるので、説明は省略するが、本実施例では、超音波振動子５の振動端５ｂの端部に突起５ｃを形成する。   FIG. 3 is an enlarged configuration diagram of an ultrasonic welder according to another embodiment of the present invention. 2 is a lower support member, 5b is a vibration end of an ultrasonic transducer 5, 6 is an anvil, 6c is an insertion hole, and 7 is a cover. The welded container 7a is an end, and since the configuration thereof is the same as that in the above embodiment, the description thereof is omitted. In this embodiment, a protrusion is formed at the end of the vibration end 5b of the ultrasonic transducer 5. 5c is formed.

このように構成した本実施例では、被溶着物の容器７の端部７ａがアンビル６の上に載置され、超音波振動子５の振動端５ｂを超音波振動させて、被溶着物７の端部７ａの上から振動端５ｂをアンビル６の挿入穴６ｃに押し込むと、超音波振動子５の振動端５ｂの端部の突起５ｃによって、被溶着物７の端部７ａの溶着突起７ｂの内側の一部７ｃだけが溶着されるので、この溶着された一部７ｃのみが剥がされて開封されることにより、容器７の端部７ａを簡単に開封することができ、又、容器７を開封した後、溶着突起７ｂを互いに合わせて、一方の溶着突起７ｂを他方の溶着突起７ｂに挿入すると、この溶着突起７ｂの形成時に溶着突起は互いに密着しているので、容器７の端部７ａを剥がして溶着突起７ｂを互いに挿入しても、簡単に抜けることがなく、抜け止めの効果を十分発揮することができる。   In the present embodiment configured as described above, the end 7a of the container 7 to be welded is placed on the anvil 6, and the vibration end 5b of the ultrasonic transducer 5 is ultrasonically vibrated, so that the weld 7 When the vibration end 5b is pushed into the insertion hole 6c of the anvil 6 from above the end portion 7a of the ultrasonic vibrator 5, the projection 5b at the end of the vibration end 5b of the ultrasonic vibrator 5 causes the welding protrusion 7b of the end portion 7a of the welded object 7 to be welded. Since only the inner part 7c is welded, only the welded part 7c is peeled off and opened, whereby the end 7a of the container 7 can be easily opened. When the welding projections 7b are aligned with each other and one welding projection 7b is inserted into the other welding projection 7b, the welding projections are in close contact with each other when the welding projection 7b is formed. Even if the 7a is peeled off and the welding projections 7b are inserted into each other, There is no kicking it, missing the effect of the stop can be sufficiently exhibited.

なお、上記実施例では、超音波振動子の振動端の端部に突起を１つ形成したが、振動端に複数の突起を設けてもよいし、又、アンビル側に１つ又は複数の突起を形成してもよい。   In the above embodiment, one protrusion is formed at the end of the vibration end of the ultrasonic transducer. However, a plurality of protrusions may be provided at the vibration end, or one or more protrusions may be provided on the anvil side. May be formed.
